Most bikes that retail for more than $600 or so will likely be very repairable. Department store bikes where the stem is integrated and has cheap components are harder to repair in that the parts typically just need to be replaced when they stop working and the metal used is so soft they tend to get chewed up easily as soon as you start working on it.
The parts will likely be held together using a combination of hex or torx bolts and very few if any use of Phillips screws. That can be a sign of a bike that is hard to repair if they’re cheaping out on parts. That being said there are some bikes made of steel and large bolts and nuts which are designed for rugged use and ease of repair in 3rd world countries.
Watching YouTube videos on bike repairs like park tools or some of the Berm Peak flip bike videos can get you an idea of what bike repair entails and some red flags.
Technically this happened is 2023. Insane nonetheless.
